SARS-CoV-2 infection in adults and HIV: an update
Aim COVID-19 pandemic caused by SARS-CoV-2 is spreading
throughout the world affecting both healthy individuals and people
with underlying immune-deficiencies. People living with human
immunodeficiency virus (HIV) consist a group multiply affected
by this universal crisis.
Methods Literature search aiming to identify relevant publications referring to the consequences of the COVID-19 pandemic in
HIV infected population.
Results A body of literature is rapidly growing in regard to epidemiological data, the interaction between HIV and SARS-CoV-2,
and clinical outcome in people living with HIV. Intensive research is warranted to identify any interactions of the co-existence of
the two viruses in the immune system of HIV infected patients as
common pathophysiology and molecular aspects are recognized.
Human relations are diminished as a result of the social measures,
and detailed recording of the consequences in this population is
needed.
Conclusion Further research could shed light on the common underlying molecular mechanisms of both conditions in an attempt to
discover treatment regimens for SARS-CoV-2 infection

Patient outcomes following surgical management of thyroid nodules classified as Bethesda category III (AUS/FLUS)
Introduction: The Bethesda classification system for reporting thyroid cytopathology is the standard for interpreting fine needle aspirate (FNA). Because of its heterogeneity and inconsistent reporting, atypia of undetermined significance or follicular lesion of undetermined significance (AUS/FLUS), known as Bethesda category III, is the most controversial category. Thyroid nodules that fall within Bethesda categories III–IV have an overall risk of malignancy of between 15 and 40%. The aim of this study was to determine the malignancy rate in Bethesda III nodules.
Material and methods: A retrospective study was performed for 1166 patients who underwent thyroid surgery for multinodular goitre (MNG) or solitary nodular goitre (SNG) in our institution between June 2010 and May 2020. Data retrieved included demographic characteristics of the patients, FNB cytology, thyroid function test results, type of thyroidectomy, and final histology results.
Results: During the study period, 29.5% (344/1166) of patients with an FNA categorized as AUS/FLUS underwent thyroid surgery. Of these 344 patients, 190 were diagnosed with MNG and 154 with SNG. Incidental malignancy was found in 35 of 190 cases of MNG (18.42%) and 31 of 154 cases of SNG (20.13%). The most common malignant tumour type in either category was the follicular variant of papillary thyroid carcinoma.
Conclusions: The current study demonstrates that patients with a FNA categorized as AUS/FLUS may have a higher risk of malignancy than traditionally believed. Reconsideration may be necessary to guidelines that recommend observation or repeat FNA in this category of patients

Risk of surgical site infections after colorectal surgery and the most frequent pathogens isolated: a prospective single-centre observational study
Aim To identify risk factors for developing surgical site infections
(SSIs) based on a prospective study of patients undergoing colorectal surgery.
Methods Between November 2019 and January 2021, 133 patients underwent elective operation for colorectal cancer in our institution. The following variables were recorded for each patient:
age, gender, body mass index (BMI), American Society of Anesthesiologists Classification (ASA class), duration of surgery, wound classification, skin preparation regimens, surgical approach,
comorbidities (hypertension, diabetes, cardiovascular disease,
respiratory disease, chronic steroid use), and pathogens responsible for surgical site infection. Univariate analysis was performed
using χ2
tests for categorical variables.
Results A total of 65 males and 68 females were enrolled. Postoperative SSI was diagnosed in 29 (21.8%) cases. Fifty five patients
were >70 years old, and SSIs were significantly more frequent in
this group (p=0.033). There were 92 patients with BMI <30kg/m2
and 87 with ASA class ≤2; SSIs occurred significantly less frequently in these patients (p=0.021 and p=0.028, respectively). Open
surgery was performed in 113 patients; 35 (out of 113; 31%) wound infections were classified as contaminated or dirty, and SSI
occurred more often in these two groups (p=0.048 and p=0.037,
respectively). Nineteen patients had diabetes and 36 used steroids
continuously; SSI was significantly more frequent in these patients
(p=0.021 and p=0.049, respectively).
Conclusion Following colorectal cancer procedures SSIs were
significantly more common among patients over 70 years old,
BMI≥30kg/m2
, ASA score>2, with diabetes and chronic steroid use,
undergoing open, dirty or contaminated surgery. Escherichia coli and
Enterococcus spp. were the two most common pathogens isolated
Cancer rate of Bethesda category II thyroid nodules
Aim Thyroid nodules are very common and may be found in
more than 50% of the population. Fine-needle aspiration cytology
(FNAC) of thyroid nodules is a very useful diagnostic tool with
high sensitivity and predictive value for diagnosis. The Bethesda System for Reporting Thyroid Cytopathology (BSRTC) uses
six categories for thyroid cytology reporting (I-nondiagnostic, IIbenign, III-atypia of undetermined significance (AUS)/ follicular
lesion of undetermined significance (FLUS), IV-follicular neoplasm/suspicious for follicular neoplasm (SFN), V-suspicious for malignancy, and VI-malignant. Our objective was to determine the
malignancy rate in Bethesda II nodules.
Methods From June 2010 to May 2020 a retrospective analysis
was performed among 1166 patients who underwent thyroid surgery for benign thyroid diseases in our institution. Thyroid cytopathological slides and Ultrasound (US) reports were reviewed
and classified according to the BSRTC. Data collected included
age, gender, cytological features, and histological type of thyroid
cancer.
Results During the study period, 44.77% (522/1166) of patients
with an FNA categorized as Bethesda II underwent thyroid surgery. Incidental malignancy was found in 1.53% (8/522) cases of
Bethesda II. The most common malignant tumour type was papillary thyroid carcinoma.
Conclusion The current study demonstrates that incidental thyroid
carcinoma can be diagnosed after thyroidectomy even in patients
with an FNA categorized as Bethesda II

Segmentectomy versus lobectomy. Which factors are decisive for an optimal oncological outcome?
Low-dose computed tomography is being used for lung cancer screening in high-risk groups. Detecting lung cancer at an early stage improves the chance of optimal treatment and increases overall survival. This article compares segmentectomy vs. lobectomy as surgical options, in the case of stage I non-small cell lung carcinoma, ideally IA. To compare the 2 previously referred strategies, data were collected from articles (40 studies were reviewed), reviews, and systematic analyses in PubMed Central, as well as reviewing recent literature. Segmentectomy could be an equal alternative to lobectomy in early-stage NSCLC (tumour < 2 cm). It could be preferred for patients with a low cardiopulmonary reserve, who struggle to survive a lobectomy. As far as early-stage NSCLC is concerned, anatomic segmentectomy is an acceptable procedure in a selective group of patients. For better tumour and stage classification, a systematic lymph node dissection should be performed
Urban thoracic trauma: diagnosis and initial treatment of non-cardiac injuries in adults.
This comprehensive review aims to delineate the prevailing non-cardiac thoracic injuries occurring in urban environments following initial on-site treatment and subsequent admission to hospital emergency departments. Our study involved a rigorous search within the PubMed database, employing key phrases and their combinations, including "thoracic injury," "thoracic trauma," "haemothorax," "lung contusion," "traumatic pneumothorax," "rib fractures," and "flail chest." We focused on original research articles and reviews. Non-cardiac thoracic injuries exhibit a high prevalence, often affecting poly-trauma patients, and contributing to up to 35% of polytrauma-related fatalities. Furthermore, severe thoracic injuries can result in a substantial 5% mortality rate. This review provides insights into clinical entities such as lung contusion, traumatic haemothorax, pneumothorax, rib fractures, and sternal fractures. Thoracic injuries represent a frequent and significant clinical concern for emergency department physicians and thoracic surgeons, warranting thorough understanding and timely intervention
Mid-term outcomes in the treatment of retroperitoneal sarcomas: a 12-year single-institution experience
Aim To present the experience from collective data regarding patients with retroperitoneal sarcomas that have been operated in and followed up by the University General Hospital of Patras in Rion, Greece, between 2009 and 2020.
Methods A retrospective analysis of adult patients treated at our hospital with a diagnosis of primary retroperitoneal sarcoma who underwent tumour resection.
Results Data from 29 patients were analysed. The mean age at diagnosis was 56.1 years; 55.2% of patients were male (n=16). Liposarcomas (on histology) were identified in 19 (65.5%) patients, leiomyosarcoma six (20.7%), and other histologic subtypes in four (13.8%) patients. Tumours >5cm were presented in 27 (93.1%) patients. Negative margins were attained in 13 (44.8%) of all patients who underwent surgical resection. Five (17.2%) patients received neoadjuvant radiation, four (13.8%) postoperative radiation, and three (10.3%) patients received both chemotherapy and radiation prior to surgery with the rest of the patients being treated with surgical excision alone. A 3-year follow-up was successful in 21 (72.4%) patients; five (23.8%) patients died. In total, 16 (55.2%) patients were found to have a local recurrence, with no significant difference in patients' age, gender, tumour size, histology, negative surgical margin (Ro) resection, neoadjuvant chemotherapy, or radiation therapy. There was a significant difference in the 3-year survival rate between patients having positive or negative surgical margins (p=0.027).
Conclusion The higher 3-year survival rate in patients with retroperitoneal sarcomas when achieving Ro resection warrant further investigation with a larger sample size across different institutions
